Technical Problem
当前的这类扶手，其上放置的书、电子设备等基本上都是平放的，这不太符合人们的使用习惯，如何更好地设计扶手的结构来调节扶手上的书、电子设备等的摆放角度，进而更好地符合使用习惯正是本申请人的目的所在
Benefits of technology
[0014]与现有技术相比，本实用新型的有益效果：由于把四个轴套两两成对作为第一合页本体和第二合页本体之间相对转动的转动轴来使第一、二合页本体构成双轴转动的同时，使轴套和转动连接块构成不可相对转动的整体和在轴套上设有能在第一合页本体和第二合页本体的阻尼孔中摩擦转动的阻尼部，这样，既可以使办公椅扶手的扶手部打开角度的调节幅度更大，又可以在180度范围内无级调节扶手部的打开角度以满足办公椅乘坐者不同时期的使用需求，因此本实用新型的结构更合理，适用性更广。
